Panhard bars resist unwanted flex and twisting, keeping the axle properly located under the chassis for improved cornering and driveability under all conditions. Adjustable options are available for centering the axle on lowered Camaros and Firebirds. The truck and SUV Panhard Bars allow for maximum rear suspension travel without bushing bind. A complement to QA1 lower trailing arms, the panhard bars include greaseable polyurethane bushings for a long, trouble-free life. Made in the USA.
